HEATING SYSTEM.

Specification of Letters Patent.

Patented Nov.- 6, 1917.

Application filed December 1 3, 1915 Serial No. 66,484.

To all whom it may concern:

Be it known that citizen of the United States, residing at Kansas City, in the county of of Missouri, have invented certain new and useful Improvements in Heating Systems, of which the following is a specification.

, My invention relates to improvements in heating systems.

It relates particularly to a system which combines hot air heating means with water or steam heating means.

One of the objects of my invention is to provide a heating system which will eliminate the distribution of dust, smoke and gas from the air which is circulated by the heating means.

Another object of my invention is to provide a heating system which may be economically installed and operated.

Stillanother object of my invention is to provide means by which the heating may be equally efi'ected throughout the house containing the system.

A further object of my invention is to provide a structure which will avoid overeating of the water employed to heat the radiators or other heating units, when one or more of such units is cut off.

Still another object of my invention is to provide a structure which will provide a maximum of draft and rapid circulation of the air employed for heating purposes.

A further object of my invention is to provide a structure which will avoid overeating of the basement or room which contains the heating mechanism.

In the accompanying drawings, which illustrate the preferred embodiment of my invention,

Figure 1 is a vertical my improved heater.

Fig. 2 is a front elevation of the same, shown connected with the radiators and rooms which it is designed to heat.

Jackson and State drum located above the fire box 2 and prov ded with an inlet or neck 6, through which the fire box discharges its gaseous products of combustion. The drum 5 is provided with the usual outlet 7 discharging into the usual smoke pipe 8.

Encircling the fire box 2 is an annular water heater 9 which has connected to it, adjacent to its lower end a cold water return pipe 10.

A hot water or steam conductor 11 is connected at one end to the water heater 9 adjacent to the upper end thereof.

The conductor 11 is provided with branches 12 which respectively connect with radiators 13.

The conductor 10 is provided with branches 14 which respectively connect with the radiators 13.

Within the drum 5 is preferably provided a central vertical partition 15, between the upper edge of which and the drum 5 is provided a space for the passage of the gaseous products of combustion.

A pivoted deflector 16, located in the inlet 6 has its lower edge secured to a horizontal rock shaft 17 which extends at its forward end to the exterior of the furnace, said forward end being) provided with a crank arm 18, Fig. 2, y which the rock shaft may be turned so as to dispose the deflector 16 in vertical alinement with the partition 15, as shown in solid lines in Fi 1, or horizontally at either side of the roc shaft 17, one of these last named positions being shown in dotted lines in Fig. 1.

Located in the drum 5 at the' side of the partition 15 which is distant from the outlet 7, is a water heater 19, to which is connect adjacent to the lower end thereof the upper end of a conductor 20. the lower end of which is connected to the conductor 10.

A conductor 21 has one end connected to the conductor 11, the other end being connected to the heater 19 adjacent to the upper end thereof.

In the operation of this portion of 1 1y invention, the hot water or steam travels from the heater 9 through the conductor 11 and its branches 12 to the radiators 13. The hot water or steam passes from the heater 19 by the conductor 21 to the conductor 11. The cold water from the radiator 13 passes by the branches to the heaters 9 and 19.

When the deflector 16 is disposed, as

14: and conductors 10 and 20 j shown in solid lines, in Fig, 1, the gaseous products ot' combustion travel upwardly the drum 5 at both sides of the partition 15, t ierchy heating the heater 19. The deflector is so disposed, when all of the radiators 13 are in operation. if desired, in extremely cold Weather, the deflector 16 may be turned horizontally to the left of the partition 15, so as to cause more of the hot gases to come in contact with the heater 19. i

If one of the radiators 13 is shut oh, the deflector 16 may be turnedto the right to the horizontal position shown in dotted lines in Fig, 1, thus cutting the heater 19 out of the path of the gaseous products of combustion, and thereby reducing the area oi the surface heated, thus preventing overheating of the Water employed for heating purposes.

Supported by the casing 1 and located Wholly above the feet"'opcning normally closed by the door3 is a vertical cold air conductor 22 haying a horizontal bottom 23 through which extends the lower end of the drain 5. i

The upper end of the conductor 22 is provided with a cold air inlet 2%, which may be covered by a grating The inlet 24 is located in a room 'a'hi h communicates with a room 2? by a door 28, which may be closed by a door cold air conductor 30 communicates its upper end with the room 27, and at its lower end it communicates with the cold air conductor 22 at a point a substantial distance above the lower end thereof,

Located within and encircled by the conductor 22 is an intermediate conductor 31, the upper end of which discharges into the room 26 and the lower end of which is disposed above and spaced apart from the bottom 23.

Located Within and spaced apart from the conductor 31 is a vertical hot air conductor 32, the lower end of which is supported upon the bottom 23 by downwardly extending lugs 33, and the upper end of which discharges into the conductor 31 at a substantial distance below the upper end of the latter, Preferably the lower end of the C01 ductor 32 is lower than the lower end of the conductor 31.

in the operation of the hot air heating mechanism just described, the cold air passes downwardly from the room 26 through the inlet 24 and between the Walls of the conductors 22 and 31. The cold air passes then up through the hot air conductor 32 and also upwardly between the conductors 31 and 32. As the air passes upwardly through the hot air conductor 32, it is heated by the drum 5, and passing by the upper end of the space which is intermediate of the conductors 31 and 32 creates a suction in said space, therey accelerating the upward draft in said space The cold air passing upwardly in said space serves as .isulator to prevent the heat passing g the Walls of tie conductors 22 and At the same time the air in said space becomes heated by radiation from the hot air conductor.

The heated air is discharged from the conductor 31 into the room 26. In case that it is desired to heat the room, the door 29 is opened, thereby permitting hot air to pass into the room 27 from the room 26, the cold air from the room 2"? passing by Way of the conductor 30 into the cold air conductor 22, Where it unites with the cold air entering said conductor through the inlet 24-. By locating the discharge end of the conductor 30 at a substantial distance above the lower end or" the conductor 22, the cold air passing downwardly in the latter assists the downward reason of the cold air insulation between the conductors and 32, the base ment or other room containing the furnace does not become (W611i eat-ed by radiation from the drum 5 or hot air conductor 32.

By locating the hot and cold air conductors Wholly above the feed inlet for the fuel, and in fact above all the inlets which lean toward and into the fire box, leaky joints around such inlets cannot discharge dust, smoke or into the air which is circulated by the air heating mechanism.

By combining my 'raproved hot air and water heating mechanisms in one system, heated by single furnace, economy of installation and or" operation is eiiected, together with an econoniizing of space. It "will he noted that the conductors 10, 11, 20 and 21 connect the heaters 9 and 19 in parallel, instead of series with each other. By means or" this parallel arrangement of the heaters, the quantity of Water heated, by utilizing the deflector 16 may be Varied Without changing the temperature of the Water located.

1 do not confine or limit my invention to the specific disposal and arrangement of the Water heaters shown described nor to the other details of construction, illustrated and described, as modifications, Within the scope of the appended claims, may be made "Without departing from the spirit of my invention.
